I am inclined to agree that it's not necessarily "wrong" - but mainly because I don't believe it to be a black and white issue. Self-segregation is beneficial to the individual - they feel like part of the group, and that reduces stress. But it certainly feels like there may be societal factors that force people to make that choice, and those may be negative. Likewise, diversity seems to me like something to be sought out. If I am only surrounded by people who are very much like me, I tend to only see problems from one perspective, or have my own personal biases reinforced.

As with most things, it is not as simple as "this is wrong." There's a lot to consider, and to me, it isn't the self-segregation that we should fight, but rather, it might be the case that we should fight the root cause of the desire to self-segregate.
